Technical Abstract

Provided is a camera lens assembly including an optical filter employing a plurality of color light emitting diodes. The camera lens assembly includes a lens module having a printed circuit board, an image sensor positioned on the printed circuit board, an IR filter, and a camera lens, the camera lens assembly. The camera lens assembly further includes a base, a lens housing positioned on an upper surface of the base for accommodating the lens module, and formed with a lens aperture at a position corresponding to the camera lens, and an optical filter positioned adjacent to the lens module for selectively transmitting or blocking a color light radiated from a plurality of color light emitting diodes through the lens aperture.

Patent Claims
8 claims

Legal claims defining the scope of protection, as filed with the USPTO.

1

1. A camera lens assembly for a mobile phone having a camera lens module including a printed circuit board, an image sensor positioned on the printed circuit board, an IR filter, and a camera lens, the camera lens assembly comprising: a base; a lens housing positioned on a base upper surface of the base for accommodating the camera lens module, and formed with a lens aperture of the lens housing at a position corresponding to the camera lens; an optical glass disposed in the lens aperture; and an optical filter positioned adjacent to the camera lens module for selectively transmitting a color light radiated from a plurality of color light emitting diodes onto the optical glass so that the optical glass transmits or absorbs a specific wavelength of light coming through the lens aperture.

2

2. The camera lens assembly as claimed in claim 1 , wherein the color light emitting diodes are provided at a position on the base upper surface to radiate the color light; and the optical filter includes a diode reflecting plate positioned adjacent the color light emitting diodes to reflect the color light onto the optical glass.

3

3. The camera lens assembly as claimed in claim 1 , wherein the image sensor and the IR filter are provided on an upper surface of the printed circuit board, and a lens mount for retaining the camera lens is installed onto the upper surface of the printed circuit board.

4

4. The camera lens assembly as claimed in claim 3 , wherein the lens housing includes a fixing opening connected to a connection provided at the lens mount.

5

5. The camera lens assembly as claimed in claim 2 , wherein the lens housing is provided with a space for accommodating the plurality of color light emitting diodes and the diode reflecting plate therein.

6

6. The camera lens assembly as claimed in claim 1 , wherein the color light includes at least one of light colors of white, red, magenta, yellow, green and cyan.

7

7. The camera lens assembly as claimed in claim 6 , wherein a yellow-light emitting diode is used as a correction filter in such a way that when yellow light is illuminated onto the optical glass, the optical glass reproduces bright and dark phases of a subject; and wherein a red-light emitting diode is used as a contrast filter in such a way that when a red light is illuminated onto the optical glass, the optical glass transmits or absorbs a specific wavelength of the light coming through the lens aperture.

8

8. A camera lens assembly for a mobile phone having a lens module including a camera lens, the camera lens assembly comprising: a base; a lens housing positioned on an upper surface of the base for accommodating the lens module, and formed with a lens aperture of the lens housing at a position corresponding to the camera lens; an optical glass disposed in the lens aperture; and an optical filter positioned adjacent to the lens module for selectively transmitting a color light radiated from a plurality of color light emitting diodes onto the optical glass so that the optical glass transmits or absorbs a specific wavelength of light coming through the lens aperture.
